MATTRESS-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 766,476, dated August 2, 1904.

Application filed December 30, 1903. Serial No. 187,206. (No model.)

To all whmn it may concern:

Be it known that I, GEORGE IV. \VAREHAM, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Mattress- Filling Machines; and I do hereby declare the following to be a full, clear, and exact description thereof.

' My invention relates to mattress-fillers.

In the accompanying drawings, Figure 1 represents a side view of my improved machine. Fig. 2 represents a plan view. Fig. 3 is an enlarged view of the front end of the same, and Fig. I is an enlarged plan view of the rear end, and Fig. 5 is a longitudinal section of the roll.

Like numerals indicate like parts in each of the views.

In the drawings, the numeral 2 designates a suitable framework for supporting the several parts of the machine. Sprocket-wheels 3 are mounted on shafts 3 3, journaled in suitable bearings at in the framework 2. The sprocketchains 5 engage the sprocket-wheels 3.

On the shaft 3 is the sprocket wheel 7, which isdriven by the chain 8, passing around the sprocketwheel 9 on the shaft 10. A gearwheel 11 on the shaft 10 meshes with the gearwheel 12 on the shaft 13. Mounted on the shaft 13 are the loose pulleys I L 1 which may be connected up by the belts 15 to a suitable source of power adapted to drive said pulleysinoppositedirections. Suitableclutch mechanisms 16 are mounted upon the shaft 13 and are adapted to be thrown into and out of engagement with the pulleys 14 for the driving of the shaft 13 in the direction desired. Secured to the chains 5 is the table 17, composed of slats 18, which give flexibility to the table to enable it to follow the chains 5 in their course. Mounted upon the table 17 is a plate 19, which may be formed of sheet metal of proper gage and of sufficient flexibility to conform to the flexible table 17 as it follows the course of the chains 5. The plate 19 is secured at its forward end to the table 17 and is connected at its rear end to the slat 20, not connected to the chains 5.

Secured to the chains 5 is the short section of slats 21, provided with the straps 22,within 30, which is connected up to the sprocketwheel 31 on the shaft 32, mounted within the arms 27 by means of the chain A crank 34 is connected to the shaft 32, and a gate 37 is secured to the outer end of the arm 35. By turning the crank 34E this gate 37 may be raised or lowered to the position shown in dotted lines in Fig. 1.

Mounted on the shaft 3 is the gear-wheel 38, which meshes with the pinion 39 on the shaft 40. Upon this shaft 40 is the sprocketwheel ll, which is connected up by the chain 42 with the double sprocket-wheel 43 on the shaft 4%. A chain 4:5 connects the other half of sprocket-wheel i3 with the sprocket-wheel 46 upon the roller-shaft 29. In this manner power is applied to rotate the roller 28.

To provide for the adjustment of the roller 28 a lever is employed, said lever being connected to the arm 62 and said arm 62 in turn being connected by the curved arm 63 with the roller-shaft. By raising the lever 60 it is apparent that the roller 28 will be moved back to the position indicated in dotted lines, Fig. l.

Extending longitudinally of the machine and mounted in suitable bearings in the frame is the shaft 47. Mounted at each end of the shaft 47 are the sprocket-wheels 18. Sprocketchains 49 connect the sprocket-wheels 4:8 with sprocket-wheels 50 and 51, journaled in the frame. Secured to the chains 49, as at 19, is the beam 52, which is adapted to move over the plate 19 transversely of the frame and which forms one of the sides of the box or receptacle within which the mattress-filling material is discharged, the opposite side 53 being stationary on the-frame. In this manner provision is made for increasing or decreasingthe width of the mattress -to be formed.- A crank 54 is secured to one end of the shaft 17, and by operating said crank it is apparent that the side beam 52 may be moved to any position desired, being attached to the chains 49.

As before stated, the roller 28 is formed of two parts telescoping each other, and the outside or inclosingsection of said roller is in position when the roller is in the position shown in Fig. 1 to be in contact with the movable side 52, so that as said side is moved inward by the chains 49 said side will also act upon the outer section of the roller 28 and carry said section with it, so that the length of the roller 28' is diminished accordingly to conform to the width of the receiving-box.

Secured to the front end of the frame 2 is the chute 55, said chute being composed of the two telescoping members 56 and 57. The upper edges of said chute-sections are curved, as at 58, to engage the rod 59, upon which said sections are adapted to slide; The lower edges of said chute-sections are bent downwardly, as at 65, and fit within the L-shaped bracket 66. The movable section 56 of the chute is also in the path of the movable side beam 52, so that said movable section 56 is moved to the same extent as said side beam 52, and said chute conforms in width to the width of the receiving-box. A table 67 stands in front of the machine in proper position with reference to the chute to receive the mattress as it is formed and passes from the said chute. A plate 68 fills the gap between the point where the plate 19 begins to turn downwardly and the mouth of the chute 55.

A pusher 69 is attached to the pusherframe 70, said frame being secured to the chains 5. The pusher 69 is formed in two parts, and the movable section has the arms 71 mounted to slide at their inner ends on the rod 72. The pusher is in the path of the side beam 52, and the movable section is moved by said beam so as to correspond to the width of the boX.

W hen my improved mattress-filler is in operation, the filling material is fed into the receiving-box, the gate 37 being thrown down into the position shown in Fig. 1 until the material has been properly arranged within the box, whereupon said gate is thrown back out of position and the machine put in motion. Thematerial supported upon the plate 19 is advanced to the roller and is fed forward by said roller into the chute 55, the projections or ribs on said roller acting to carry the material forward and prevent the roller slipping over the same. As the plate 19 advances, being secured to the slatted table 17, said plate follows the course of said table and accordingly bends down and passes back under and toward the rear end of the machine. As the machine continues in operationthe plate 19 advances until the material has all been carried through the chute 55 into the ticking, engaging said chute'until the pusher 69 finally .pushes the last of the-material through the chute into the ticking, when the mattress is completed. The-roller 28 is then thrown back to the position indicated in dotted lines in' Fig. 1, and by reversing the machine by means of clutches 16 the chains 5, carrying the plate 19, are reversed and the plate 19 is brought back to its normal position in readiness to receive another supply of the filling material, when the operation is again repeated. In this manner the plate 19 forms a flat even surface for the conveying of the filling material to the chute; but instead of passing through the chute and into the ticking, as in former patents granted to me, said plate having performed its function of feeding the material properly to the chute follows the direction of the chain and by simply reversing the direction of movement of said chain is brought back into position for use again without having to withdraw it from the ticking, as was the case in my former patents.

As the table 17 is formed of slats, these slats will separate as they pass around the sprocketwheels, and to compensate for this increased diameter around which the plate 19 bends and to keep said plate stretched the spring 25 is employed, said spring acting to hold taut that part of the table which is advancing toward the sprocket-wheels and preventing its sagging down with the chain so as to cause a depression in the bottom of the receiving-box, and thus prevent the proper feeding and distribution of the filling material. The slat 20 not being connected with the chains 5 is free to be separated from the table 17 by the cables 2 1 and the spring 25. If desired, the machine may be operated by hand, a crank 75 being provided for this purpose.

What I claim is 1. In a mattress-filler, the combination with a suitable frame, of a chute, a traveling metallic sheet or plate adapted to carry the material toward said chute, and means for defleeting said plate.

2. In a mattress-filler, the combination with a suitable frame, of a chute, a traveling metallic sheet or plate adapted to carry the material toward said chute, and means for turning said plate back on itself.
